Spectroscopic study of the Planetary Nebulae Ap 2-1
Abstract
We have carried out an spectroscopy study of the Planetary Nebula Ap 2-1, obtaing for the first time its radial and expansion velocity, we have also analysed the spatial variation of the electronic density, and we have detected a growth toward the centre. Finally we discuss its physical nature, which have been questioned since some years ago; there are arguments in favour/against of HII Regions-Planetary Nebulae. FULL TEXT IN SPANISH
